The electrical device is installed in the box, and the fan is arranged in the box for ventilating and cooling the electrical device in the box.
[0003] When used in places with severe dusty environments such as deserts and Gobi, sand and dust may enter the interior of the box through the ventilation holes of the box. Therefore, in the related art, a sand-proof device such as filter cotton is usually installed at the ventilation holes of the box to prevent sand and dust from entering the box.
[0004] However, when a certain amount of sand and dust accumulates on the surface of the filter cotton, the ventilation volume of the filter cotton will be reduced, thereby affecting the heat dissipation effect of the entire energy storage device, and the maintenance cost of the filter cotton is high. Utility Model Content
[0005] The problem solved by the utility model is how to effectively prevent sand and dust in the air from entering into the box of the energy storage device without reducing the ventilation volume of the energy storage device.
[0006] To solve the above problems, the utility model provides a sand-proof device, which is applied to energy storage equipment. The energy storage equipment includes a box body, and the sand-proof device is used to be arranged at the ventilation port of the box body, including at least one sand-proof component; the sand-proof component includes a shell and at least two baffle members, and the shell is provided with an air inlet and an air outlet, at least two of the baffle members are arranged in sequence and staggered in the shell along the direction from the air inlet to the air outlet, and an "S"-shaped air duct is formed between the at least two baffle members and the side walls of the shell, and the two ends of the "S"-shaped air duct are respectively connected to the air inlet and the air outlet.
[0007] Optionally, among any two adjacent baffle members, one baffle member is connected to the top wall of the shell but not to the bottom wall of the shell, and the other baffle member is connected to the bottom wall of the shell but not to the top wall of the shell.
[0008] Optionally, in any two adjacent baffle members, the bottom end position of the baffle member 22 connected to the top wall of the shell is lower than the top end position of the baffle member connected to the bottom wall of the shell.
[0009] Optionally, the baffle member includes a baffle portion and a connecting portion which are arranged at an angle, and the connecting portion 222 is arranged parallel to the inner wall of the shell and is connected by a first fastener.
[0010] Optionally, the air inlet and the air outlet are arranged opposite to each other, and the heights of the top wall and the bottom wall of the shell gradually decrease from the air outlet to the air inlet.
[0011] Optionally, the anti-sand component further includes a protective net, and the protective net is arranged between two adjacent baffle members.
[0012] Optionally, the sand-proof device includes multiple sand-proof components, and the multiple sand-proof components are arranged in a vertical direction and connected in sequence; the sand-proof device includes a common side panel for forming a side wall of one side of the "S"-shaped air duct of the multiple sand-proof components, and the common side panel is provided with a sand discharge port connected to the "S"-shaped air duct of each of the sand-proof components.
[0013] Optionally, the sand-proof device further comprises a connecting angle plate, and the connecting angle plate is provided on one side of the common side plate of the sand-proof device and on a side opposite to the common side plate, and the box body and the shell are fixedly connected via the connecting angle plate.
[0014] Optionally, the height of the bottom wall of each shell gradually decreases in a direction from away from the common side plate to close to the common side plate.
[0015] Compared with the prior art, the sand-proof component of the utility model includes a shell and two baffle members arranged in the shell. Since at least two baffle members are arranged in the shell in sequence and staggered along the direction from the air inlet to the air outlet, when the air containing sand and dust outside the energy storage device enters the shell from the air inlet of the shell, since at least two baffle members form a certain angle with the air flow direction entering the shell, the at least two baffle members staggered in the shell can effectively block the sand and dust entering the shell laterally, so that the sand and dust in the blocked air fall on the inner bottom wall of the shell due to gravity, so as to prevent the sand and dust from entering the interior of the box through the air outlet of the shell.
[0016] Since the top wall, bottom wall and at least two baffle members of the shell are combined to form an "S"-shaped air duct, not only can the at least two baffle members block the sand and dust in the air in the shell for multiple times at different positions, thereby improving the blocking effect of sand and dust in the air, but also the clean air after the sand and dust are removed continues to flow in the "S"-shaped air duct, and enters the box body from the air outlet of the shell through the ventilation port of the box body, so as to achieve the heat dissipation and cooling effect on the electrical devices arranged in the box body; in other words, the utility model arranges at least one sand-proof component at the ventilation port of the box body to replace the filter cotton of the related technology, thereby ensuring the heat dissipation and cooling effect on the electrical devices of the energy storage equipment without reducing the ventilation volume of the box body, and effectively reducing the maintenance cost of the sand-proof device.
[0017] In addition, the energy storage device also includes a fan, which can be installed in the box. The noise generated during the operation of the fan will also be continuously reflected on the baffle members in the "S"-shaped air duct, so that the two baffle members can also effectively reduce the noise propagation of the fan, thereby correspondingly solving the problem of high fan noise in the energy storage device.
[0018] The utility model also provides an energy storage device, comprising a box body and the anti-sand device as described above, and also comprising an electrical device, wherein the electrical device is arranged in the box body.
[0019] Since the energy storage device includes the above-mentioned anti-sand device, the energy storage device at least has all the technical effects of the anti-sand device, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.
[0033] In order to solve the above technical problems, Figure 1 and Figure 2As shown, an embodiment of the utility model provides a sand-proof device, which is applied to energy storage equipment. The energy storage equipment includes a box body 1, and the sand-proof device is used to be arranged at the vent 11 of the box body 1, and includes at least one sand-proof component 2; the sand-proof component 2 includes a shell 21 and at least two baffle members 22, and the shell 21 is provided with an air inlet 211 and an air outlet 212, at least two of the baffle members 22 are sequentially spaced and staggered in the shell 21 along the direction from the air inlet 211 to the air outlet 212, and an "S"-shaped air duct is formed between the at least two baffle members 22 and the side wall of the shell 21, and the two ends of the "S"-shaped air duct are respectively connected to the air inlet 211 and the air outlet 212.
[0034] It should be noted that the shell 21 can be a parallelogram shell structure or a rectangular shell structure; the four side walls of the shell can form an "S"-shaped air duct with at least two of the baffle members 22, so that the two baffle members 22 can be installed in the cylindrical structure; therefore, the baffle member 22 and the side walls of the shell 21 along the first direction (vertical), such as the top wall or the bottom wall, are arranged at an angle, which can be understood as the baffle member 22 is vertically arranged relative to the shell 21, and the vertical arrangement is not limited to the baffle member 22 being completely parallel to the first direction, but may also refer to the baffle member 22 being at a certain angle to the first direction; similarly, the two baffle members 22 are staggered in the shell 21, which can be understood as one baffle member 22 is installed on the inner top wall of the shell 21, and the other baffle member 22 is installed on the inner bottom wall of the shell 21, and the two baffle members 22 are staggered in the vertical direction (that is, not on a vertical plane).
[0035] The shell 21 is installed on the box body 1, and an air outlet 212 is provided on the shell 21 at a position corresponding to the vent 11 of the box body 1, and the air inlet 211 can be provided on a side wall of the shell 21 away from the box body 1, and can also be provided on a side wall of the shell 21 adjacent to the box body 1, so the position of the air inlet 211 of the shell 21 is not specifically limited.
[0036] The anti-sand component 2 of the present embodiment includes a shell 21 and two baffle members 22 arranged in the shell 21. Since at least two of the baffle members 22 are arranged in the shell 21 in sequence and staggered along the direction from the air inlet to the air outlet, when the air containing sand and dust outside the energy storage device enters the shell 21 from the air inlet 211 of the shell 21, since at least two baffle members 22 form a certain angle with the air flow direction entering the shell 21, the at least two baffle members 22 staggered in the shell can effectively block the sand and dust entering the shell 21 laterally, so that the sand and dust in the blocked air fall on the inner bottom wall of the shell 21 due to gravity, so as to prevent the sand and dust from entering the interior of the box 1 through the air outlet 212 of the shell 21.
[0037] Since the top wall and bottom wall of the shell 21 and at least two baffle members 22 together form an "S"-shaped air duct, not only can the at least two baffle members 22 block the sand and dust in the air in the shell 21 for multiple times at different positions, thereby improving the effect of blocking the sand and dust in the air, but also the clean air after the sand and dust are removed continues to flow in the air duct and enters the box body 1 from the air outlet 212 of the shell 21 through the vent 11 of the box body 1, so as to achieve the heat dissipation and cooling effect on the electrical devices arranged in the box body 1; in other words, the utility model provides at least one sand-proof component at the vent 11 of the box body 1 to replace the filter cotton of the related technology, so as to ensure the heat dissipation and cooling effect on the electrical devices of the energy storage equipment without reducing the ventilation volume of the box body 1, and effectively reduce the maintenance cost of the sand-proof device.
[0038] In addition, the energy storage device also includes a fan, which can be installed in the box 1. The noise generated during the operation of the fan will also be continuously reflected on the baffle members in the "S"-shaped air duct, so that the two baffle members 22 can also effectively reduce the noise propagation of the fan, thereby correspondingly solving the problem of high fan noise in the energy storage device.
[0039] In addition, the energy storage device also includes a fan and an electrical device. The fan can be arranged on the box body 1, for example, it can be arranged on the top plate of the box body 1, the side plate corresponding to the sand-proof device, or the side plate away from the sand-proof device. The electrical device is installed in the box body 1 so that the fan works to generate negative pressure in the box body 1, so that the air containing sand and dust in the box body 1 enters the interior of the shell 21 through the air inlet 211 of the shell 21.
[0040] At least two baffle members 22 in the shell 21 can form a similar "maze unit", and the noise generated by the fan during operation will also be reflected multiple times in the "maze unit" in the "S"-shaped air duct to effectively reduce the propagation of noise, which to a certain extent solves the problem of high noise of the cooling fan.
[0041] Specifically, adjacent baffle members 22 may be arranged approximately in a central symmetric manner to form a similar “maze unit.” Multiple adjacently arranged baffle members 22 may be in a “convex” shape or other shapes, which are not specifically limited herein.
[0042] In one embodiment of the present invention, Figure 3 As shown, among any two adjacent baffle members 22, one baffle member 22 is connected to the top wall of the shell 21 but not to the bottom wall of the shell 21, and the other baffle member 22 is connected to the bottom wall of the shell 21 but not to the top wall of the shell 21.
[0043] It should be noted that when the sand and dust in the air entering the shell 21 collides with the two adjacent baffle members 22 respectively connected to the top wall and the bottom wall of the shell 21, it is blocked and falls on the inner bottom wall of the shell 21 due to gravity, and the other baffle member 22 adjacent to the bottom wall of the shell 21 can effectively temporarily store the blocked sand and dust to prevent the blocked sand and dust from continuing to move toward the air outlet 212 with the air.
[0044] In one embodiment of the present invention, Figure 3 As shown, among any two adjacent baffle members 22 , the bottom end position of the baffle member 22 connected to the top wall of the shell 21 is lower than the top end position of the baffle member 22 connected to the bottom wall of the shell 21 .
[0045] It should be noted that, combined with Figure 2 As shown, the side wall of the shell 21 in the first direction, such as the positive direction of the Z axis, is the top wall of the shell 21, and the side wall of the shell 21 in the first direction, such as the negative direction of the Z axis, is the bottom wall of the shell 21; similarly, one end of the baffle member 22 in the positive direction of the Z axis is the top end of the baffle member 22, and one end of the baffle member 22 in the negative direction of the Z axis is the bottom end of the baffle member 22.
[0046] The bottom end position of a baffle member 22 arranged on the top wall of the shell 21 is lower than the top end position of the other baffle member 22 arranged on the bottom wall of the shell 21. In other words, the relative ends of two adjacent baffle members 22 staggered along the first direction (vertical) are negatively spaced, which can ensure that each baffle member 22 can block sand and dust in the air to further improve the anti-sand effect.
[0047] In an embodiment of the present invention, at least two baffle members 22 are arranged in parallel or at an angle to each other.
[0048] It should be noted that the number of baffle members 22 can be flexibly increased or decreased according to actual on-site conditions; and at least two baffle members 22 can be arranged in parallel or at a certain angle, for example, some baffle members 22 can be arranged obliquely.
[0049] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the baffle member 22 includes a baffle portion 221 and a connecting portion 222 which are arranged at an angle. The connecting portion 222 is arranged parallel to the inner wall of the housing 21 and connected via a first fastener.
[0050] It should be noted that since the baffle portion 221 and the connecting portion 222 are arranged at an angle, for example, the end portion of the baffle portion 221 along the first direction, such as the top end or the bottom end, is bent to form the connecting portion 222, the mechanical strength of the baffle member 22 can be enhanced; and the connecting portion 222 can be arranged parallel to the inner wall of the shell 21 along the first direction, such as the top wall or the bottom wall, so that when the connecting portion 222 is connected to the side wall of the shell 21 along the first direction through the first fastener, the connection area between the connecting portion 222 and the shell 21 can be increased to improve the connection stability between the baffle member 22 and the side wall of the shell 21 along the first direction.
[0051] The first fastener may be a bolt fastener, a rivet, etc., which is not specifically limited here.
[0052] In one embodiment of the present invention, Figure 2 As shown, the air inlet 211 and the air outlet 212 are arranged opposite to each other, and the height of the top wall and the bottom wall of the shell 21 gradually decreases from the air outlet 212 to the air inlet 211.
[0053] It should be noted that, since the height of the top wall and the bottom wall of the shell 21 gradually decreases from the air outlet 212 to the air inlet 211, in other words, the top wall and the bottom wall of the shell 21 have a downwardly inclined surface from right to left, so that when the air containing sand and dust outside the box body 1 enters the air inlet 211 of the shell 21 from left to right, the downwardly inclined surfaces of the top wall and the bottom wall of the shell 21 can directly block the sand and dust originating from the upper right side of the shell 21, so as to reduce the amount of sand and dust entering the shell 21; and, since the air entering the shell 21 passes through the baffle members 22 at different positions during the flow process, the sand and dust blocked by the baffle member 22 at this time falls on the inner bottom wall of the shell 21 due to gravity, and flows downward along the inner bottom wall of the shell 21 to the bottommost position of the inner bottom wall of the shell 21, so as to lower the top position of the sand and dust in the shell 21, so as to avoid the subsequent air entering the shell from driving the dust that has been blocked in the shell 21 to continue to flow, and further ensure the sand-proof effect of the air entering the shell 21.
[0054] In one embodiment of the present invention, Figure 5 As shown, the sand-proof component 2 further includes a plurality of protection nets 23 , and the protection nets 23 are arranged between two adjacent baffle members 22 in the two baffle members 22 .
[0055] It should be noted that Figure 5The rear side wall of the entire shell 21 is removed to show the structural schematic diagram of each baffle member 22 inside the shell 21; by arranging a protective net 23 between two adjacent baffle members 22 among the multiple baffle members 22, so that the larger dust particles in the air are blocked by the baffle members 22, the remaining smaller dust particles are blocked by the protective net 23 during the flow in the air duct, which is not only beneficial for protecting against sand and dust with a specified particle size, but also can block the larger dust particles that are not blocked by the baffle members 22 again, further improving the anti-sand effect.
[0056] Among them, the protective net 23 has multiple sieve holes, which can effectively block more dust; as for the size of the sieve holes on the protective net 23, it can be flexibly selected according to the size of the dust particles in the area where the energy storage device is located, and no specific limitation is made here.
[0057] In one embodiment of the present invention, Figure 5 As shown, the sand-proof device includes a plurality of sand-proof components 2, and the plurality of sand-proof components 2 are arranged in a vertical direction and connected in sequence; the sand-proof device includes a common side panel 3 for forming a side wall of one side of the "S"-shaped air duct of the plurality of sand-proof components 2, and the common side panel 3 is provided with a sand discharge port 213 connected to the "S"-shaped air duct of each of the sand-proof components 2.
[0058] It should be noted that, since multiple sand-proof components 2 are arranged in a vertical direction, and the air outlets 212 of multiple sand-proof components 2 are connected to the ventilation holes 11 of the box body 1, multiple sand-proof components 2 have multiple air inlets 211, and multiple air inlets 211 are arranged in a vertical direction. Therefore, on the basis of ensuring that the box body 1 has a certain amount of air intake, the air containing sand and dust on the outside of the box body 1 enters the shell 21 of the corresponding sand-proof component 2 simultaneously from the multiple air inlets 211 arranged in the vertical direction, so as to increase the number of baffle members 22 to block more sand and dust in the air, thereby further improving the sand-proof effect.
[0059] A side wall adjacent to the air inlet in the vertically arranged multiple sand-proof components 2 can form the common side panel 3, and a sand discharge port 213 connected to the "S"-shaped air duct in each sand-proof component can be opened on the common side panel, so that dust can be blocked and discharged into the shell 21 from the sand discharge port 213, effectively avoiding the accumulation of sand and dust in the shell 21.
[0060] In one embodiment of the present invention, Figure 6 and Figure 7 As shown, the sand-proof device further includes a connecting angle plate 4 , and the connecting angle plate 4 is provided on one side of the common side plate 3 of the sand-proof device and on the side opposite to the common side plate 3 , and the box body 1 and the shell 21 are fixedly connected via the connecting angle plate 4 .
[0061] It should be noted that when the sand-proof component 2 is assembled with the box body 1, the side wall of the box body 1 and the shell 21 can be respectively connected by connecting the two ends of the angle plate 4, so that the sand-proof component 2 is fixed at the position of the vent 11 of the box body 1 through the connecting angle plate 4; wherein, the connecting angle plate 4 can be connected to the box body 1 and the shell 21 by welding, rivets, or bolt fasteners.
[0062] Of course, the sand-proof device may include a plurality of connecting angle plates 4 , and the plurality of connecting angle plates 4 may be distributed on the front and rear sides of the shell 21 , thereby improving the assembly stability of the sand-proof component 2 and the box body 1 .
[0063] Specifically, the connecting angle plate 4 may be an L-shaped structure, so that the two sides of the L-shaped structure are more tightly connected to the shell 21 and the box body 1 respectively.
[0064] In one embodiment of the present invention, Figure 5 As shown, the height of the bottom wall of each shell 21 gradually decreases from away from the common side plate 3 to close to the common side plate 3.
[0065] It should be noted that, since the bottom wall height of each shell 21 in the sand prevention device gradually decreases from away from the common side plate 3 to close to the common side plate 3, the sand and dust that enters the shell 21 and is blocked by the baffle member 22 and falls on the inner bottom wall of the shell 21 due to gravity can slide from a higher position of the inner bottom wall of the shell 21 to a lower position for accumulation. A sand discharge port 213 can be opened at the corresponding position of the common side plate 3 and the inner bottom wall of the shell 21, so that the sand and dust at the lower position of the inner bottom wall of the shell 21 can be discharged from the shell 21 through the sand discharge port 213. In this way, on the basis of satisfying a certain ventilation volume for the box body 1, not only the sand and dust entering the air in the shell 21 can be blocked and killed, but also the blocked dust can be discharged from the shell 21 through the sand discharge port 213, thereby effectively preventing the accumulation of sand and dust in the shell 21.
[0066] Example description, combined with Figure 5 As shown, the front end position of the inner bottom wall of the shell 21 is higher than the rear end position of the inner bottom wall, and a sand discharge port 213 is opened on the common side plate 3 at a position corresponding to the baffle member 22, so that after the sand and dust in the shell 21 is blocked by the baffle member 22 and falls on the inner bottom wall of the shell 21, the sand and dust on the inner bottom wall of the shell 21 can slide from the front end to the rear end and be discharged from the shell 21 through the sand discharge port 213 on the common side plate 3.
[0067] The utility model also provides an energy storage device, comprising a box body 1 and the anti-sand device as described above, and also comprising an electrical device, wherein the electrical device is arranged in the box body 1.
[0068] It should be noted that the electrical device can be arranged in the box 1. If the energy storage device is an energy storage cabinet, the electrical device can be a battery pack. If the energy storage device is a busbar cabinet, the electrical device can be a busbar, a switch device, etc.
[0069] The energy storage device also includes a fan, which can be arranged at a position corresponding to the electrical device in the box body 1 to facilitate the operation of the fan, so as to generate negative pressure in the box body 1, and suck the air outside the box body 1 into the shell body 21 from the air inlet 211 of the shell body 21, and the dust in the air is blocked by the baffle member 22 to form clean air, and then the clean air continues to flow along the air duct and enters the box body 1 through the air outlet 212 through the vent 11. Then, the clean air entering the box body 1 continues to flow under the action of the fan, so as to discharge the heat generated by the electrical device from the fan to the outside of the box body 1, thereby achieving heat dissipation and cooling of the electrical device in the box body 1.
[0070] The energy storage device has all the technical effects of the anti-sand device, which will not be elaborated here.
[0071] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
